JOSEPH G. BIRCH, OF NEWTON, MASSACHUSETTS, ASSIGNOR TO THE PHOENIX MANUFACTURING COMPANY, OF SOUTH BERW'ICK, MAINE.

TELESCOPIC SUPPORTER FOR CURTAINS, DRAPERIES, DISPLAY-CARDS, &c.

SPECIFICATION forming part of Letters Patent N o. 645,543, dated March 20, 1900. Application filed OOlOlJI' 14, 1899.v Serial No. 733,603- (NO models) To all wiz/ont t may concern:

Be it known that I, JOSEPH G. BIRCH, a citizen of the United States, residing at Newton, in the county of Middlesex and State of Massachusettsdiave invented certain new and useful Improvements in Telescopic Supporters for Curtains, Draperies, Display-Cards, and other Things, of which the following is a specification, reference being had'therein to the accompanying drawings.

Figure l is a View showing one of my new telescopic supports in place between Windowjambs and in that position adapted to sup- Fig. 2 is a holder. Fig. 3 is a perspective view of the annular wedge. Fig. at shows a modification of the preferred form of construction whereby an adjustable head of the holder is held operatively in place.

The object of my invention is to produce an improved telescopic holder forsupporting window-curtains, portieres, advertisements, articles of manufacture, garment hooks and supports, and anything else desired, the telescopic members of my new holder being very nearly of the same diameter and adapted to be firmly locked in adjusted position.

In the drawings illustrating the principle of my invention and the best mode now known to me of applying thatprinciple,A is the inner telescopic member, and B the outer telescopic member, within which member A`is received.

Member A is provided with an annular wedge D, which is of a uniform interior diameter and slides freely on member A. The outer surface of the annular wedge D is tapered to a thin edge d, which is toward the inner end of the outer telescopic member B. The outer'end of the telescopic member Bis tapered outwardly at b on the inside, so as to nicely receive the annular wedge when it is moved into the inner end of the-outer member B to lock the members A and B together, the member A being preferably a close-sliding tit within the chamber of theY member B.

Member A is providedwith a head A, the outer end of which is preferably faced with rubber. Head A is preferably, but not nec essarily, mounted non-adjustably'( on member A. The outer end of member B is provided with ahead B', which is telescopically mounted on member B. Head B is normally held distended with reference to member B by means of a spring b', mounted in the outer 55 end portion of member B and bottomed conveniently upon the block h2, loosely within the chambered shank or end portion b3 of member B. Head B' is accordingly provided v with a tubular shank b3, having one or more 6o (in this case two) diametrically opposite lengthwise slots bsx, A pin b4 passes through member B into and through the vslots 53X and holds block b2 loosely in place as a support for the inner end of the spring b.

Member Bis preferably a hollow cylinder, as shown. The pin b4 holds the shank b3 of head B in place. In accordance with myinvention at least one of the heads referred to is combined with its adjacent telescopic meni- 7o ber by means of an interposed spring, which` normally holds the head outwardly. It will be plain to all mechanics that either or both of these heads may be mounted yieldingly on the telescopic members invarious ways, and 7 5 I do not intend to confine my invention to the precise mode shown of making the distensi ble head. Head B is preferably provided at its outer end with a yielding pad, so that the holder may be put u p between window-jambs 8o or the like without marring the woodwork or other parts against which the ends are pressed.

In putting up holders embodying this invention it may be supposed that the left hand will grip member A, with the thumb upon the annular wedge, the annular wedge being at a slight distance from the inner end or mouth of member B, and that the right hand will grip the member B the holder being so held and shortened topermit the heads to pass be- 9o tween opposed jambs or the like, and the members A and B moved to lengthen the holder with sufficient force to force the movable head B inwardly against the tension of the spring b', and when the telescopic members A and 95 B have been sufficiently distended to cause the spring to exert a strong pressure the annular wedge is moved into the mouth of member B readily by the thumb of the left hand, thus locking the members A and B firmly toroo gether and allowing the spring to exert its full distending force to keep the holder firmly in place. To remove the holder if it has been thus put in place, it is only necessary to move it endwise in the direction of the spring, and thereby compress the spring slightly or enough to shorten the holder sufficiently for easy removal. Thereupon the meinberB may be readily pulled away from the Wedge and off memberA for the removal of the curtains or the like.

In Fig. 4, showing a modification, the adj ustable head B is held in telescopic member B by a pin f through walls of member B and diametrically-opposite slots f in shank f2 of head B', shank f2 having a close sliding it in the chamber of member B. A disk or other abutment f3 for the spring f4 is mounted within the chamber of member B at a suitable distance from that end which receives the shank f2, and the distending-spring f4 is mounted between abutment f3 and the inner end of `in presence of two witnesses.

shank f2, the latter resting on the outer end of the spring, which keeps the head B normally distended with reference to member B. The mode of operation of this form is the same in effect as that of the preferred construction.

What I claim is- In an adjustable supporting device,the com bination of an inner telescopic member hav-- -end of the outer member; and elastic means which keep the head on said shank normally `distended in relation to said outer member which is provided with a mouth within which' said annular wedge is received; said outer telescopic member being endwise movable, in

either direction, between and in relation to said wedge and shank.

In testimony whereotI I affix my signature JOSEPH G. BIRCH.
